About These Birds

Anna's Hummingbird

Anna's hummingbird is the most common hummingbird along the Pacific coast and one of only three species resident in the United States year-round. Males perform spectacular dive displays, plummeting from 40 meters and pulling up with a loud chirp produced by tail feathers. Their body temperature can drop to near ambient at night to conserve energy.

A medium-sized hummingbird (10-11 cm) found in montane forests from Mexico to Honduras at 1,000-2,500 m. Green plumage with cinnamon flanks. Nectarivore of pine-oak and cloud forest. Named after the German collector Moritz Wagner.
